0.5 gram common salt is dissolved in 25 g of water. Calculate the concentration in term of mass by mass percentage of the solution.

Text Solution

Verified by Experts

Mass of solute (common salt) = 0.5 g
Mass of solvent (water) = 25 g
Mass of solution = (0.5 + 25)g = 25.5 g
Now, Mass percentage of solution
= `("Mass of solute")/("Mass of solution")xx100`
= `0.5/25.5xx100`
= 1.96%
